Crude characterization for HYSIS model

[TonySA]

I'm looking for a procedure/tool to convert a crude assay sheet to a TBP curve (or ASTM) in order to fill my models of HYSIS.

Thanks for your help in advance.

Hello Tony,

In a Basis Environment window, there is Oil Manager tab with button that moves you to Oil Environment.
Add an assay in oil environment and enter all available data from crude assay. Is this what you are searching for?

Regards,

Thanks EmmanuelTop.

However, the problem I encounter is different. To illustrate it, I enclose the data I have:

ATMOSPHERIC DISTILLATION:
IBP -> C5; FBP -> 65 => 3.8%
IBP -> 65; FBP -> 100 => 5.0%
IBP -> 100; FBP -> 150 => 7.0%... etc.

VACUUM DISTILLATION:
IBP -> 370; FBP -> 475 => 15%
IBP -> 475; FBP -> 525 => 5.7%... etc.

These data cannot be fed directly to HYSIS as the available input assays are TBP, ASTM distillations, chromatograph and EFV.

How can I convert these data to any of HYSIS input formats?

What methods have you used for crude oil analyses?

I have just a crude assay. I understand this is an standard way to characterize crudes, but the data from the crude assay cannot be fed directly to HYSIS (or at least I don't know how to do it)

PVTsim from CALSEP (

http://www.calsep.com)

is one of the most recognised regression tools in the business.

Its the engine behind OLGA (flow model) for properties and many large oil companies uses PVTsim. If you work for an oil company i will bet that you have license for this or a similar product (one other name that i recall is infochem)

Best regards

Hi!!

You have TBP distillation it should be entered like:

Assey percent Temperature (degC)
3.8 65
8.8 100
15.8 150
etc....

Milutin

Thanks Milutin... Regarding vacuum distillation, is there any standard vacuum pressure in which crude assay data are reported? When I specify the TBP distillation I also have to specify the (vacuum pressure).

Regards, Tony

 

[Milutin]

If you don't have pressure data for your vacuum distillation shown, it means results are calculated for atmospheric pressure, so use atmospheric conditions when you enter data to hysys.
